lfhe maehine illustrated is intended for a lieneh niaehine. and the frame is illus-'- lrated as having Short legs 16. (it' course the inat'hine can he made to .stand at an)v height that may he desired. The bottoni i7 of the trame is provided with a Central boss 19 in whieh is tightlv fitted-.as by being driven in. a hollow spindle lll. which spindle poswases a donhle Vlunetion presently de- .sei-ihed. heinovahlv fitted to the upper end ol the spindle i9 is a mandrel 20. Mounted on the hollow spindle 19 is the sleeve portion 2l ot the Cam earrier 0r easing. the bottom' 22 of Said earrier or easing having a rotative hearing upon the bottom 17 ot' the frame. and having the eylindrieal or peripheral easing portion 23. Secured to this earn carrier or casing are an outer cam rin Q4 and an innerl cam ring 25, the vertical height of these two rings and the outer shell as hereinafter described and 23 being substantially the saine as the sleeve portion 21 on the spindle 19. This structure provides for a center of support at. the center of maximum strain: that the bearing fer the cani casing' is located in the horizontal plane of operations of the cams, instead of in a lower plane as in the patent above referred to. This provides for greater stability and less wear ot' the inachine.

The other function of the hollow spindle 10 is to enable it to be employed as a stationary guide through which a cable or other core to have a woven covering applied thereto can be fed upwardly. ln other words, the hollow spindle l!) serves as a noni'otarv guide for such core or cable and tlnr-tore produces no tendency, during the operation of thi.` looni, to rotate such core er cubic. When it is desired to weave a tubular fabric having no core, the upper end of the hollow spindle 19 is employed to receive the plug of a mandrel 20. about the upper end of which the weaving,r then takes place.

Secured to the bottoni Q2 of thtv camA suppoii. a spur gear l0 with which meshes an idle inter ediate pinion 27 mounted upf i stud S that. is supported by the bottinr, if. Mcshing with the pinicn J7 is a pinke '11i which is secured upon a vertical shaft liti mounted in suitable bearings provided h) the frame of the loom. said shaft Il() liavifel also i bevel pini' .i Iii meshing with :i similar' pinion Si sieurcd to a driving' shaft i354. friction clutch driven device ot' a well known forni i` employed for the shaft L aufl is sutlici -iit lv illustrated in Fig. il. in which l indicates thc cone ineinliei which is secured to tlic cuter end of .slia'l 553, a driven belt [alley Ili' having an inni-r surface to colpcuilc with t'lic coin; lil when the pulley 535 is shifted iatcrally relaii\ely to the cone itt.

tixed relative positions so that there can be no binding of the slides which reciprocate vertically in the Ways 44 formed in the sides ot' said guides.

llach of the guides 41 is provided with a pair of oppositely inclined wings 45 which, when the entire. series of guides 41 are in asse bled positions, forni a horizontal circular track or way for the shuttle carriers, such track or way being of course interrupt; ed or cut by the spaces between the guides 41, but not in any such manner as to inter fere with the travel of the shuttles.

'l`he base'plates 46 ot' the shuttles are tapered at cach end as indicated at Fig. 11, so that they may be driven as hereinafter described, and in the saine manner as describeil and claimed in the patent above iiiriitioiied. To the back of each plate 46 is secured a lower fixed gib 47 and an upper the wings 45 which constitute the shuttle track. The gib 48 is adjusted by means of cone tipped screws 49.

Each plate 46 has secured thereto a bobbin frame 50 provided with bearings .71 for the spindles of the usual paper tubing which supports the ordinary universal wound bobbin.

To keep the bobbin thread in close contactV with the friction drum or shell G1 hereA inafter described, I provide a tension consisting of a presser 52 which is a U-shaped frame pivoted at 53 to the plate 4G, one or more springs .74 (see Fig. fl) being employed to hohl the horizontal portion of the presser frame in contact with the surface of the bobbin. This presser prevents the bobbin from revolving too freely and consequently disturbing the close contact between the thread and the drum er shell G1 mentioned. Said presser acts. of course7 on a bobbin which varies in diameter as the thread is drawn otf, but since the spring 5l shortens as the presser moves downwardly, the friction created by the presser becomes gradually less.

lleferring especially lo Figs. 2, il and 7, it will be seen that un ai'ni .35 projects fron the plate 4U. ln said arm is rigidly mounted a pin or spindle .ifi ha\ing a cone base. 57 and also having an opposing concbushing 58 which is .slidably mounted on the spindle but .si-curul so as not to rotate thereon. spring 5ft is coiled about tlic projecting end el' the spindle. and a cap or nut (it) havingr a `which may be "ses fitting" the concs 57,

tbc threaded end ot' the spindle and enables the pressure ol'v spring' fr!) against conc-buslr ing I# to be varied. l\ drum or `shell (3l (see lig, i') having internal conc-shaped end wi-estas is mounted on the si mille, said re- 511 the cap 10, the degree of friction which will retard rotation ol' the drinn or shell (Si By adjust- .eifically to the may be varied. l :lo not limit myself speeleinents shown, as .said elements may possess any Suitable forni that will enahle the neeessary friction to be obtained. to the arln 55 a bar or plate having a plurality ot' guides ti?, formed therein. Three of Said guides are shown as eyes or holes, two of thetn having openings leading away from the drinn (Sl and one of thein having an opening faeing toward said druni. This structure provides a tension for the shuttle thread `whieh provides no direet grip action on the thread and consequently will perniit a knot to paas freely. The thread is led from the bohbin through one of the eyes (S3 nearest to the arin 55, then around the drinn (Sl which is preferably roughened, then through the intermediate eye (33, then again around the drinn (il. then through the third eye (337 and then through in eye in the outer end of a stoponotion lever G4 which is pivotally connected at ('15 to the frame 50. as best shown ir Fig. i.

Owing tio the guidesl lili being open, and thetapering forni given to the end of the nut or rap (it), the thread may be easily passed and located as deeerihed. The esperial objeet of the several guidex tl ie to hold the several coils ,spared and enable the pret'- erably roughened .Qurt'aee ot thtI drinn til to result in unit'orin tension. while without such guides the thread wrapped several tintes about the drinn (31 would. owing to it spiral winding, tend to run ott' at one end of the drinn.

While the function of this portion otl the loom is ubstantially the laanie as i|nilar deviees in the patent referred to, yet thi` struetiii'e involves a ver-v material feature of my present improvement in that thi` takingup 1 ot' the .alaek thread ol the warp is eaused by meelianism wliieh is loi-ated entirely out ide f ot the path of rotation ot' the shuttle. o a l to render the lshuttle hobhins more aeee, ihle. 4

A\ piti 953 (Figs. l and 5l projeets downwardly l'roni member 02 through a slot .tti iiilthe member 91. and eaid pin l5 is eonnected to a pin 0T piojeetingdirwnwardly l from i'neinber 01, by a sprin 98, the tension l of this spring being to always draw the pin 95 to the end of the slot 9o nearest the pin 0T. and conheonently normally holding the eoinponnd ringV so that the two members will move together ander normal operating conditions. The oscillation ot' the compound ring is etfeeted as t'ollowsf pin 90 (Figs. L and 8) projects downwardly from the member 91 and is eoiineeted by rod 100 with the .strap ot an eeeentrie 101, the latter being mounted to rotate with a gear 102 which, by means ot' intermediate compound gearing 102ir` is driven by a pinion 101 on shaft 50. lt will therefore be understood that during' the operation ot' the looni. the eseentric will eau e constant short oseillations of the compound ring 01. trl. llut if a varp breaks and a pin 89 dropl into the hole 94 whieh is being' eon tantly reeiproeated underneath it, then sueh pin -ervesy to lock the member 92 from oseillating'. and only the member 91 will oseillate. The ring 90 is provided with upwardly projeeting ribs 103. 10G ovei whieh the warps l are drawn. and these ribs are ot Sneh height. relatively' to the length of the pim4 S0 t'roin their lower ends. to the portiom whieh rest upon the warpsq that when the loom i ruiininf. and running' properly. all otE the pins 80 are y upported so that their lower end are above the plane ol' the top ol' member 11;.

'l`he outer end of thelever 110 is i eonneeled by a lnltl 114 to a lever 115 pivloted at 11V and having a eatch 11T at its jother end. lrelerably the eonneetion be' l tween the link ll-l and lever 110 ia a Slotted ene i that the rateh l 1T may be raiaed wit-liont material opposition` when the niaehine ds being #turted to hereinafter deSerilied. 'l`he one or tapered end 7l of the pin Ti, ot' the lillinja- \top motion la-reinhet'ore dexi'iilietl. project to auch a position that when the spring', T3 proieets the pin T3. said tapered end T4 will enyxeew the underide of `lever lli between its pi .a and the eateli end, so as to raise it will be understood at this point that whether af filling or shuttle thread breaks, or a warp breaks, the lever 115 will be actuated to raise the catch 117.

A hand lever 118 (Figs. 3 and 8), pivotally supported at 119, has a lug or shoulder 120 that is normally engaged by the catch 117, the lever 118 being held in the position Which it occupies when the loom is running, by said catch, a spring 121 Shifting the lever when 'the catch releases it. The lower portion of lever 118 has a projection or stud 122, preferably ball-shaped at its end, which engages upper arm of elbow lever 37. This arc slot is eccentric to the axis of pivot 119, the eccentricity being such that when the shoulder 120 is released by the catch 117, upon the breakage of either warp or weft, the spring 121 throws thc'leve'r'l18 so that the stud 122, traveling along the slot 123, oscillates the elbow lever 37 to effect the stoppage of the loom.

The operations of the several parts of the loom having been explained 'in connection with the description of the structure thereof, further explanation of the operation of the loom as a n hole will not be necessary further than to state that, in general, it is the saine as that of the loom described and claimed in my patent hereinbefore referred to.

It will be understood, of course, that when either the breakage of a filling thread or a warp thread has caused the actuation of lever 115 of spring 121 the hand lever 118 causes the separat-ion of the driving clutch members, and the machine stops. If the breakage Was in a filling thread. the leading of the thread back again through the eye of lever (i4 (Fig. 2)' will put the mechanism in condition to enable the machine to be started again by simply throwing the lever 11S (Fig. S) over so that its Shoulder 120 will be re-ngaged bythe catch 117. It the stop page was due to the breakage of a. warp, then the supply of a continuous warp thread again will elevate the hook pin 89 which it dropped, and then the operator, by means of the handle 125 of pin 95 (Fig. 5) will restore the ring members '91, 92, to their normal relative positions so that the pin 10T (Fig. 8) will return down the incline or cam 111 and permit the spring 112 to raise the lever 110A and return the catch 117 to position to be rengaged by the shoulder 120 of the lever 11i..
